Rust-Oleum Marine Coatings Anti-Slip Additive Half Pint

You don't need much to make the surface anti slip

Great stuff, mix before every roller dip before spreading. Did one layer , then did a layer of paint over the top for added durability and makes it less harsh.

I used it & mixed it with full gloss,oil based paint to paint the floor of my RV Shower & Toilet.Easy to use!Worth every penny!

I am pretty impressed with how well this stuff works. I first tried to broadcast it onto the paint afterwards like some reviewers suggested, but found it too hard to get even. So my advice would be to mix it with your paint in small batches so you can stir it alot to get even grit distribution. I wanted a really rough surface so I rolled it on and that worked well for my application. Much nicer than using sand, imo. I went a bit radical and because I wan't very concerned with the appearance of my final surface (max grip was more important) and I actually did a second coat where I broadcast a little extra grit onto fresh wet paint and then rolled that in. So it wasn't as even as one would usually want, but the amount of grip is pretty amazing. I bought in from Amazon and pretty pricey for such a small amount, but if you can find it locally it is far cheaper because the free shipping is not built into the price. For me the conveniece of buying online is worth it.

Used it mixed with paint and it has worked very good. Lots of grip and not sharp on bare feet
